Inspect all the harness connections. Make sure that the connectors are clean and tight.
Check the connectors for proper mating. Ensure that all the seals are present and in place.
Check the harness for signs of damage or abrasion.
Check the wires at the connector. Ensure that the wires are secured tightly into the connector. Perform a 45 N (10 lb) Pull Test on each of the wires that are associated with the circuit. Take care not to pull the wire out of the connector.
Check the exposed wires at the connectors for nicks or signs of abrasion.
Check for moisture inside the connector.
Check the connectors for dirty or corroded contacts.
Check each pin and each socket of the machine harness connectors. Ensure that the contacts are properly installed. The contacts should mate correctly when the two pieces of the connector are placed together.Note: See Testing and Adjusting, "Electrical Connector - Inspect" for more information.Expected Result:The machine harness connectors are tight and free of corrosion.Results:
OK - The machine harness connectors are tight and free of corrosion. Proceed to Test Step 2.
NOT OK - The machine harness connectors are in need of repair.Repair: Repair or replace the machine harness.Proceed to Test Step 7.Test Step 2. CHECK THE VOLTAGE OF THE DATA LINK.
Turn the key switch and the disconnect switch to the ON position.
Connect Cat® ET and verify which ECM has communication diagnostics activated. At each of the ECM modules or devices that are not communicating, use an electrical spoon to measure the voltage. One at a time, measure the voltage of connector contact CAN + and CAN - to frame ground.Note: Do not use the shield wire as a ground.Expected Result:Both voltage measurements are between .5 VDC and 4.5 VDC.Results:
OK - The voltages of the wires for the Data Links are correct. Proceed to Test Step 5.
NOT OK - The voltage is greater than 4.5 VDC.Repair: Repair or replace the harness.Proceed to Test Step 7.
NOT OK - The voltage is less than 0.5 VDC. Proceed to Test Step 3.Test Step 3. CHECK FOR A SHORT TO GROUND.
Turn the key switch and the disconnect switch to the OFF position.
